The Observatory Enhances Regional Relative Humidity Information Services

7 March 2023

The Hong Kong Observatory (HKO) has enhanced the regional weather information services today (7 March) by adding real-time relative humidity information from seven automatic weather stations, located respectively at Hong Kong Park, Shau Kei Wan, Kowloon City, Kai Tak Runway Park, Clear Water Bay, Pak Tam Chung and Tai Lung (Figure 1).

In Hong Kong, relative humidity may vary a lot on different days. Usually in autumn, the dry monsoon will cause the relative humidity in Hong Kong to drop. When it comes to spring time, under the influence of humid maritime airstream, the relative humidity will climb. More relative humidity information will allow the public to grasp the changes in weather. The most recent 24-hour relative humidity information can be accessed through the “Regional Weather in Hong Kong” webpage. The information will also be available in the mobile application "MyObservatory" later.
